PTD-DBM Reconstitution Calculator
Reconstitute a 5 mg vial of PTD-DBM with 2.5 mL of bacteriostatic water for a concentration of 2.00 mg/mL — meaning one unit on a U-100 insulin syringe (0.01 mL) holds 20 mcg. Adjust the inputs below for your own vial and dose.

PTD-DBM mg-to-units quick reference
At the default 2.00 mg/mL (5 mg in 2.5 mL), draw the following units on a U-100 insulin syringe:
| Target dose | Volume | U-100 units |
|---|---|---|
| 250 mcg (0.25 mg) | 0.125 mL | 12.5 units |
| 500 mcg (0.50 mg) | 0.250 mL | 25.0 units |
| 1000 mcg (1.00 mg) | 0.500 mL | 50.0 units |
Frequently Asked Questions
How do I reconstitute PTD-DBM?expand_more
Add 2.5 mL of bacteriostatic water to the 5 mg PTD-DBM vial for a concentration of 2.00 mg/mL. Inject the water slowly down the vial wall and swirl gently — do not shake.
How many units is a PTD-DBM dose on an insulin syringe?expand_more
At 2.00 mg/mL, one unit on a U-100 syringe (0.01 mL) holds 20 mcg. Divide your target dose in mcg by 20 to get the number of units to draw.
What is the typical PTD-DBM research dose?expand_more
PTD-DBM is typically dosed at 0.5-1 mg/mL topical to scalp (~250-1000 mcg per application) in research protocols. See the full titration schedule on the protocol page.
